CHARLES HENRY DILLON, OF NORTH ATTLEBOROUGH, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO JOHN Q. HENNIGAN, OF SAME PLACE.

FLUSHlNG-VALVE.

SPECIFICATION forming part of Letters Patent No. 410,541, dated September 3, 1889. Application filed April 23, 1889. Serial No. 308,326. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES HENRY DIL- LON, of North Attleborough, county of Bristol, State of Massachusetts, have invented an Improvement in Flushing-Valves, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to flushing-valves especially adapted to be used in the tanks of water-closets, and has for its object to construct the valve as will be described, whereby a water seal is provided against the escape of sewer-gas into the house or building.

My improved flushing-valve is of the class known as slow-closing valves, and is simple in construction, compact in size, and durable in operation.

The peculiar features in which my invention consists will be hereinafter pointed out in the claims at the end of this specification.

Figure 1 is a vertical longitudinal section of a sufficient portion of a tank and a flushing-valve embodying my invention to enable my invention to be understood. Fig. 2 is a top or plan view of the valve-seat, the valve being removed; Figs. 3 and 4, details to be referred to, and Fig. 5 a detail showing the valve as open.

A represents the bottom of a tank of any usual construction, such as now commonly employed in water-closets. The tank-bottom A is provided with an opening or orifice, into which is screwed or otherwise secured a nipple a of a preferably cylindrical casting or shell a, forming the discharge or outlet orifice for the tank, the edge a of the said shell forming the valve-seat.

The casting or shell a is provided with a hollow crossbar a preferably extended diametrically across said shell, and provided, as herein shown, with upturned arms or nozzles a, which are preferably extended above the valve-seat, for a purpose to be hereinafter described.

The hollow cross-bar cfiis provided near its center, as herein shown, with a nipple b, which extends up into a tube orpipe 1), herein shown as screwed into a threaded flange or collar 11 011 the said cross-bar.

pipe I), to form with the said pipe an out-let- A passage b of small-or contracted area.

The spindle or pipe 11 is made longer than the pipe Z), and has secured to or forming part of it at its upper end, as herein shown, a hollow cap orbell-shaped castingb of such size that its lower edge or rim lies below the top of the pipe I). The hollow spindle at its lower end is inserted through and secured to a metallic disk or plate d, provided with, preferably, a series of slots or openings d.

The metallic disk d has fitted upon it a leather or other washer d constituting the valve, the said washer being provided at or near its circumference with an annular groove d", (see Fig. 5,) into which the edge of the casting 0/ extends when the valve is closed or seated.

The hollow spindle is surrounded by a pipe 6 of larger diameter, which is herein shown as screwed upon an annular flange e of a disk or plate 6 fitted upon the valve (P, the said pipe constituting the overflow-pipe and forming with the spindle b an overflow-passage e', which communicates through the slots d with the outlet a of the tank.

The pipe I) is provided, as shown, with a ball-valve e normally resting upon the top of the nipple b, the vertical movement of the said valve being limited, preferably, by a wire 6 extendedacross the pipe I).

The bell-shaped casting or cap I) has fastened to it one end of the ordinary pull-chain 6 only a portion of which is shown in the drawings, but which may be of ordinary construction.

In operation the valve (1 is raised from its seat by pulling upon the chain 6 thus permitting the water in the tank to flow through the shell a into the discharge-pipe connected with the basin. (Not shown.) As the valve is raised, Water is drawn through the hollow arms a and cross-barsa into the pipe 1'), and when the pressure is relieved from the pullchain the water in the pipe I) is prevented from running back by the ball-valve 6 which closes the nipple b, so that when the valve (1 closes by gravity the excess of water drawn into the pipe I) is forced down through the passage 12 into the hollow casting or shell a, and thence into the discharge-pipe. In this manner the valve is made to operate as a slow-closing valve.

By extending the bell-shaped casting or cap Z2 below the upper end of the pipes b e a water seal or trap is formed as a safeguard against sewer-gas entering the house or build ing. 7

In case of accident to the supply-valve the surplus water admitted to the tank is permitted to pass off through the overflow-passage e and slots 01' into the dischargapipe.

It will be noticed that the pull or chain c is connected to the bell-shaped cap substantially over the center of thewalve, so that when pressure is exerted upon the said chain the lifting power is applied to the center of the valve, thereby obviating side friction between the parts and obtaining a perfectlybalanced valve.

The hollow arms a are preferably extended above the valve-seat a so that when the valve is opened the impurities which settle to the bottom of the tank will not enter the said arms, but only the clear water.

It will be noticed that the valve is opened a distance proportional to the amount of pull, and the use of set-screws in the tank to limit the extent of opening of the valve is obviated, and also the speed of the valve in closing is constant, and set-screws to govern the amount of opening of relief-valves, as in ordinary construction, are dispensed with.

I claim 1. Ina flushing-valve, the combination,with a hollow casting or shell provided with ahollow cross-bar having an outlet,.of a pipe selow andcovering the mouth of the said overv flow-pipe, substantially as described.

2. In a flushing-valve, the oombination,with a hollow casting or shell provided with a hollow cross-bar having an outlet and provided with arms extended above said shell, of a pipe secured to said cros s-bar aboutsaid outlet, a valve to control said outlet, a hollow spindle fitted loosely over said pipe, a valve secured to said spindle and provided with a slot, an overflow-pipe, and a cap or casting secured to said spindle and extended below and covering the mouth of the said overflow-pipe, substantially as described.

In a flushing-valve, the coinbinatiomwith a hollow casting or shell provided with a hollow cross-bar having an outlet, of a pipe secured to said cross-bar about said outlet, a valve to control said pipe, a hollow spindle fitted loosely over said pipe, a valve secured to said spindle and provided with a slot, an overflow-pipe, and a cap or casting secured to said spindle and extended below and cover-,

ing the mouth of the said overflow-pipe, and a chain or pull connected to said cap substantially over the center of the said valve,whereby a direct pull upon the valve is obtained, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
